These customs combine some of the Marvel’s heroes most popular characteristics with Harley-Davidson most popular models.

For instance, the Black Widow Iron 883 is “all blacked-out, stripped down custom aggression…[and] stands alone, an iconoclast, like the solitary Black Widow herself,” while the Hulk’s Fat Boy Lo is “big, mean and eye-popping… squat, super strong and ready to unleash [its] superpowers.” There’s even a Spider-Gwen-themed bike, highlighting a relatively new addition to the Marvel canon.

Unfortunately, these amazing bikes aren’t for sale. Australia and New Zealand residents can enter to win one by voting for their favorite design here, but as for fans in the rest of the world – we’re out of luck for now.
